SITRANS LR250 with mA/HART
118 Operating Instructions, 10/2019, A5E32220602-AG
Fill Rate per Minute (2.4.2.)
Defines the maximum rate at which the reported sensor value is allowed to decrease. Allows
you to adjust the SITRANS LR250 response to decreases in the actual material level. Fill
Rate is automatically updated whenever Response Rate is altered.
Options
Range: 0 to 99999 m / min.
Response Rate (2.4.1.)
Fill Rate per Minute (2.4.2.)
*
Slow
0.1 m/min (0.32 ft/min)
Medium
1.0 m/min (3.28 ft/min)
Fast
10.0 m/min (32.8 ft/min)
Altered by:
Response Rate (2.4.1.)
Related parameters
Units (2.2.1.)
Enter a value slightly greater than the maximum vessel-filling rate, in units per minute.
Sensor value is the value produced by the echo processing which represents the distance
from sensor reference point to the target. See
Sensor Mode (2.2.2.) for an illustration.
Empty Rate per Minute (2.4.3.)
Defines the maximum rate at which the reported sensor value is allowed to increase. Adjusts
the SITRANS LR250 response to increases in the actual material level. Empty Rate is
automatically updated whenever Response Rate is altered
.
